Athletic Club 25/26 Third Jersey

New Balance goes for a daring and modern look with the third kit. The base is a sleek, dark charcoal gray with red detailing that feels fresh and urban. A subtle gradient pattern mimics the folds of a Basque flag, creating texture and visual interest without overpowering the minimalistic design.

Red piping along the collar and sleeves injects the club’s iconic color, while the New Balance logo and sponsor appear in a clean, understated white. The Athletic crest is redesigned in a monochrome style to fit the kit’s modern, streetwear-inspired aesthetic.

This third jersey is clearly aimed at younger fans and those who want something different yet connected to club roots.
